These aren’t the first time the new Revolt gravel bikes are in public, though, as Brendan Johnston rode a pre-production Revolt Advanced Pro at the Unbound Gravel 200 earlier this year.

Some notable new features on Giant’s 2025 model year Revolt range are internal cable routing and enhanced storage compartment access. Giant’s Contact AeroLight stem guides cables into the frame, creating stealthier cable routing to improve aesthetics. Better access to the down tube storage cavity is a real win for fatigued gravel riders when they need to quickly and easily access tools, spares, or snacks – even with gloved fingers. Here's everything we know about Giant's best gravel bike.

Flip-chips and big tyres 

Recognising that gravel bike riders might desire to vary wheelbase, depending on riding terrain, the Revolt now features an adjustable rear dropout flip-chip. 

These Revolt flip-chips allow for 10mm of wheelbase adjustment. Riders can choose either more length for stability when riding with frame bags or on long, loose descents. Or trim the wheelbase for more agile riding characteristics. 

The flip-chip adjustment also influences tyre clearance. In its ‘short wheelbase’ ‘setting, Revolt has a 45mm tyre clearance, which grows to 53mm in the long wheelbase configuration. That creates an interesting scenario if you are on an adventure ride and encounter muddy conditions. In a sense, riders in the short setting who need emergency mud clearance on a ride could switch to the extended wheelbase setting for a bit more clearance – depending on conditions. 

Reference geometry numbers for the Revolt are head angles that vary between 70-, 71-, and 71.5-degrees for sizes XS, S, and M. The M/L, L and XL Revolt frames sit at a 72-degree head angle.

Frame details

Giant knows gravel bikes often become adventure off-road touring bikes, during vacation season. To increase the Revolt's carrying capacity, integrated top tube, fork and rear dropout mounts assist with securing the frame and fork bags in place. 

Frame design details to reduce rider fatigue include dropped seatstays and Giant’s Contact D-Fuse seat posts and handlebars. Featuring a ‘D-shaped' composite structure, these contact points help to reduce terrain vibration. For riders who prefer conventional round-shaped seatposts, or want to run a dropper, there are traditional 30.9mm options.
